Abstract
HRP was found with a direct electrochemistry at carbon nanotube microelectrode. The adsorbing HRP could transfer electron directly at CNT compared with common carbon electrode material. It was calculated that the transfer coefficient α was 0.57, and heterogeneous electron transfer rate constant was 2.48±0.03 s−1. It was found that the adsorbing HRP still keeps its catalytic activity to H2O2.
